Best Oil Catch Cans for the 2024 Ford Mustang (S650)

An oil catch can for the 2024 Ford Mustang is a small billet reservoir that plumbs into the PCV system to trap oil vapor, fuel, and moisture before they reach the intake — and on the seventh-generation S650 Mustang, it is one of the smartest first modifications you can make. The Gen 4 Coyote 5.0L V8 makes 480 horsepower (486 with the active-valve performance exhaust) and 415 lb-ft of torque, while the Dark Horse pushes 500 horsepower and the 2.3L EcoBoost turbo four delivers 315 horsepower and 350 lb-ft. All three engines vent crankcase blow-by straight back into the intake tract, and because they use direct injection, no fuel washes the intake valves clean. A catch can is the fix. At NLP Performance in Tampa, FL, these kits are among the first parts new S650 owners add, so we pulled together the direct-fit options worth buying, their real specs, and how to install and maintain them.

Why the 2024 Mustang Needs an Oil Catch Can

Every 2024 Mustang uses a positive crankcase ventilation (PCV) system that routes blow-by gases — a mist of oil vapor, unburned fuel, and water — back into the intake so they can be re-burned. That mist coats intake valves, the throttle body, and, on the EcoBoost, the intercooler with a sticky carbon film over thousands of miles. On a port-injected engine, fuel spraying across the back of the valve constantly scrubs those deposits away. The Gen 4 Coyote and the 2.3L EcoBoost both rely on direct injection, which sprays fuel straight into the cylinder, so nothing cleans the valve. An oil catch can sits inline on the PCV circuit, slows the vapor, lets the oil droplets coalesce and drop into a reservoir, and passes only clean air back to the intake.

The payoff is measurable. Documented results from 2024 Mustang GT owners show catch cans collecting a visible amount of oil and moisture by the first 1,000-mile oil change — blow-by that would otherwise have recirculated through the intake and combustion chamber. With the Gen 4 Coyote running a 12.0:1 compression ratio and a new dual-intake, dual-throttle-body induction system, keeping that intake tract clean protects long-term valve health, preserves throttle response, and matters even more once you add a tune, forced induction, or track use.

The 2.3L EcoBoost owner has an extra reason to care: a turbo engine pushes oil-laden blow-by through the charge-air system, so contamination can coat the intercooler core and lower the effective octane at the cylinder, nudging the 315-horsepower four toward knock under boost. Whether you drive a 480-horsepower GT, a 500-horsepower Dark Horse, or the EcoBoost, a PCV-side catch can is cheap insurance that pays off every mile the engine runs.

Top Pick: K&N 2024 Ford Mustang Catch Can / Oil Separator

For the 5.0L V8 GT and Dark Horse, the K&N 2024 Ford Mustang Catch Can / Oil Separator (part number knn81-0833) is the best value on the market at $119.51. It is a vehicle-specific, direct-fit unit that mounts to the factory PCV port with the supplied hardware — no cutting, no universal fittings, and a clean OEM-style look under the hood. K&N backs it with a limited lifetime warranty, and it installs in under an hour with basic hand tools.

Best Premium V8 Option: Mishimoto 2024+ Mustang V8 Catch Can

If you run a tuned, boosted, or track-driven 5.0L V8 and want the most aggressive oil separation available, the Mishimoto 2024+ Ford Mustang V8 Oil Catch Can (PCV Side, part number misMMBCC-MUS8-24) is the upgrade. At $204.95 (down from $225.00), it is a 100% billet 6061 aluminum can with M16 x 1.5 threaded ports, an internal baffle and air diverter, and a 50-micron bronze filter element that forces blow-by to give up nearly all of its oil before returning clean air to the intake. Mishimoto backs it with a lifetime warranty, and the compact can is designed to bolt to the factory PCV side of the Gen 4 Coyote.

Best for EcoBoost: Mishimoto 2024+ 2.3L EcoBoost Catch Can

The turbocharged 2.3L EcoBoost has its own PCV-specific answer: the Mishimoto 2024+ Ford Mustang 2.3L EcoBoost Oil Catch Can (PCV Side, part number misMMBCC-MUS4-24) at $236.95 (down from $261.00). Turbo engines pull hard vacuum and push more blow-by through the PCV system, and oil that reaches the charge air can lower the effective octane and invite knock. This kit uses the same 100% billet 6061 aluminum can and 50-micron bronze filter as the V8 unit but with EcoBoost-specific brackets and lines. It is the direct-fit way to keep the 315-horsepower turbo four's intake and intercooler clean, and it carries Mishimoto's lifetime warranty.

Driving a 2018–2023 S550 Mustang instead? The proven predecessor is the K&N 18-23 Mustang GT 5.0L catch can, and EcoBoost owners of that generation can browse our full lineup of intakes, separators, and induction parts in the engine components collection.

2024 Mustang Oil Catch Can Comparison

Here is how the three direct-fit 2024 Ford Mustang catch cans stack up by engine fit, construction, warranty, and price so you can match the right kit to your car in one glance.

Which one should you buy? For most 5.0L V8 owners, the K&N at $119.51 is the smart default — direct-fit, lifetime-warrantied, and the least expensive way to protect the intake. Step up to the Mishimoto V8 can at $204.95 if your GT or Dark Horse is tuned, boosted, or tracked and you want the 50-micron bronze filter doing the heavy lifting. If you drive the 2.3L EcoBoost, the Mishimoto EcoBoost PCV-side kit at $236.95 is the direct-fit choice engineered for the turbo four's higher blow-by.

How to Install and Maintain Your Catch Can

A 2024 Mustang oil catch can installs in under an hour with basic hand tools, and every kit here is a bolt-on that reuses the factory PCV connections. Here is the process we follow on the lift at NLP Performance:

1. Let the engine cool and locate the PCV line on the passenger side of the intake — this is the crankcase-vent line that carries oil vapor back to the intake.
2. Mount the bracket to the supplied factory bolt location so the can sits upright with room to remove the reservoir.
3. Route the inlet and outlet hoses so the can intercepts the PCV flow: crankcase vapor enters the can, clean air exits to the intake.
4. Double-check every clamp for a sealed, leak-free connection — a loose PCV line will throw a vacuum-related code.
5. Verify at idle that there are no leaks, then drive normally.

For maintenance, check the can after the first 1,000 miles to see how quickly it fills for your driving style. Most 2024 Mustangs go 2,500–3,500 miles between empties, so draining it at every oil change is a safe rhythm. Because these are billet aluminum cans with a drain, emptying takes a minute and the Mishimoto units let you clean the 50-micron bronze filter for repeat use. Catch cans are a manufacturer-supported style of modification — Ford Performance sells its own — and because they do not permanently alter emissions equipment, they are widely used on daily-driven Mustangs.
